NAME

SYNOPSIS

DESCRIPTION

The
strncat()
function appends not more than
n
bytes (a null byte and bytes that follow it are
not appended) from the array pointed to by
s2
to the end of the string pointed to by
s1.
The initial byte of
s2
overwrites the null byte at the end of
s1.
A terminating null byte is always appended to the result.
If copying takes place between objects that overlap, the
behaviour is undefined.

RETURN VALUE

The
strncat()
function returns
s1;
no return value is reserved to indicate an error.
